The natural result is vagueness on all religious and metaphysical subjects. This is a characteristic of savages all over the world. Nor is it limited by any means to them. Recent investigations have established the evolution of some at least of the majestic figures of the Olympian Pantheon from not merely rude but vague and nameless personalities; and to the very end of Hellenic religion, unknown gods and dim, indefinite heroes continued to be honoured not merely in every country place, but in Athens herself. The Arabs of Moab have professed for many generations the religion of the Prophet. Yet they have the feeblest apprehension of that great Allah in whom they are supposed to believe. When questioned on his nature, his abode, his occupation, they usually answer: “We do not know.” One of them told a missionary: “It is said that Allah is like an old man with a white beard, but I do not know where he dwells; it is asserted that he is above,” pointing to the sky. They also honour numerous beings called by the generic name of _Wely_ (protector or friend), who are identified with rocks, trees, and other holy places. Even of these, however, {15} their ideas are obscure. Like the local hero of the Greeks, the _Wely_ is not as a rule individualized with a personal name. Who he is in most cases is unknown. His exact connection with the spot where he is honoured is equally unknown. Some Arabs say that it is he who gives vigour to the sacred tree; others declare that he dwells beneath it, or that he dwells in the branches and the leaves; but Allah knows.[15.1] And the pious reference to Allah and his knowledge is sufficient for the Arab.
